Patented Mar. 24, 1931 UNITED STATES -PATENT OFFICE WILLIAM D. ANTRIM, FGLOUCESTER, NEW JERSEY, vASSIGNOIR. TO ROBERTS & MANDER STOVE COMPANY,OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA OVEN FORRANGES Application filed February 19, 1930. Serial No. 429,697.

The object of this invention is to provide means by which the door of anoven will fit snugly in the opening of the oven without requiring amachine finish of the parts. The

invention is adapted to the doors of ovens of either gas, electric, orcoal ranges.

In the accompanying drawings:

Figure 1 is a transverse sectional plan view of a portion of an oven anda door in the closed position;

Fig. 2 is a vertical sectional View;

Fig. 3 is a perspective View of part of the oven door frame;

Fig. 4 is a perspective view of one of the l5 flexible strips which aresecured to the frame; Fig. 5 is a View of a portion of the oven shown inFig. 1, with a flexible strip extended,

this being the position when the door is open; and

Fig. 6 is a view of a modification of the invention.

Referring to the drawings, 1 is the oven of a gas range in the presentinstance. 2 is the facing frame, which is at eaclrside and at 2 the topof the oven door opening in the present instance. 3 is the lining of theoven and 4 is the outside metal casing, and between the lining and thecasing is non-conductive material 5 in the present instance.

"i0 The particular construction of the oven forms no part of the presentinvention and may be modified as the demand requires.

The oren door consists of a frame 6, open at the center in the presentinstance, and in the opening is a sheet metal plate 7, which underlapsthe inner edges of the frame. 8 is the inner plate of the oven door.This plate has beveled edges 9, which are offset at 10 as shown, so asto fit back of the flange 11 of the frame. Between the frame 6 and theplate T and the inner plate 8 is a non-conductive lining l2 of anysuitable material.

The outer ends of the space occupied by the non-conductive material 5 ofthe oven struc# '15 ture, is closed b v bending over the lining plate 3.as at 3a and bending the outside plate 4 at 4a. Back of the two bentportions of thc plates 3 and 4 is a metallic strip 13, having threadedopenings to receive the screws 14.

These screws pass through a flange 2a of the oven facing frame 2, thetwo bent sections 3o y and 4a of the oven plates, and into the metallicstrip 13, securing the said parts firmly together.

In order to make a tight joint between the door and the oven frame,flexible metallic strips 15 are secured to the sides of the oven frameand to the top thereof, so as to surround the oven door opening. Themetallic strips are made as shown in Fig. 4 and each strip 60 has aslotted portion 16, which fits between the flange 2a of the oven and theframe of the oven. The strip 15 is slotted in the present instance at 17for the screws 14. By slotting the strip, the strip can be placed inposition, after the other. parts of the range are assembled, by simplybacking-off the screws 14 and forcing the portions 16 of the strip intothe space between the body of the oven and the facing frame. The portion18 70 of the strip is beveled preferably on the same bevel as theportion 9 of the door. The outer end is turned inwardly as at 19 andthis portion is arranged to slide against a portion 21 of an inner plate22 within the body of the 75 oven.

When the door is in the open position, then the strip 15 moves outwardlyto the position shown in Fig. 5. IVhen the door is closed the doorstrikes the strip 15 and pushes it 80 into the position shown in Fig. 1,making a close contact between the door and the strip. The strips arepreferably located on three sides of the oven door opening. The ovenbottom 23 has a raised flange 24 at its outer 95 edge which comes intoclose contact with the door when it is in the closed position. Thisflange also acts to hide the hinge openings in the casing from view. Insome instances the flexible strip may be located on the door in im placeof on the frame of the oven, as shown in Fig. 6, without departing fromthe main features of the invention. In this instance the stop 15a iswelded or otherwise secured to the inner plate 8a of the oven door.

I claim:

1. The combination in an oven, of a body portion; a fralne in front ofthe body portion and enclosing the oven opening; screws eX- tendingthrough the frame and into the body 10o portion and holding the frame tosaid body portion; flexible strlps, each angular in crosssection, onesection of each strip having a, beveled face, the other sectionextending between the frame and the body of the oven and secured to theoven by the said screws; and a door having a beveled surface, whichresses against the beveled portions of the exible strips when the dooris closed, making a substantially tight t between the oven and the door.

2. The combinationy in an oven, of a body portion; a frame located atthe front of the body portion and enclosing the oven opening; screwssecuring the frame to the body portion; a flexible strip, angular incross-section, one portion of the strip being slotted to pass over thescrews which secure the frame to the body portion of the oven, theslotted portion of the strip extending between the frame and the body ofthe oven, the other portion of the strip being beveled and having itsouter edge turned in; a plate within the oven, against which theturned-in portion of the strip rests; and a door arranged to close theoven opening and having a beveled surface arranged to rest against thebeveled surface of the strip, so as to cause the strip to yield and forma tight joint between the door and the oven casing.

3. The combination in a range, of a frame having an oven; a door hingedto the frame at the lower edge of the oven opening; flexible stripslocated between the two sides and the top of the oven frame and the doorto seal the space between the two parts when the door is closed; and anoven bottom plate having a flange extending to the oven frame andarranged so that the door will be in contact with the iange when closed.

WILLIAM D. ANTRIM.
